The toe-supporting means illustrated herein is generally the same as that disclosed in Letters Patent of the United States No. 1,962,141 granted June 12, 1934 upon an application iled in the name of A. Eppler and comprises a member 24 (Fig. 2) adjustable in guideways 25 secured to the top surface of the base member 20..y Mounted on the member 24 is a block 28 arranged to be adjusted vertically by means of a wedge 30. The wedge is adjusted by means of a screw S2 threaded into the wedge and having a handle 54 (Fig. 4) secured to its outer end for turning it. Collars 36 secured to the screw 32 engage opposite faces of a bracket 38 secured to the member 24 and prevent lengthwise movement of the screw so that the wedge is moved in or to the block 28 as the screw is turned thereby to raise or lower the block. Supported on the block 28 is a toe rest40 comprising a rubber pad 42 hollowed out yto receive the toe end oi the shoe and a holder 44 on which the pad is mounted. The holdery 44 is so mounted on the block 28 as `to permit it to adjust itself to the shoe about an axis extending laterally of the shoe and located substantially at the shoe-engaging face of the pad 42.

The heel-supporting means comprises a block ,45 adjustable toward and away fromthe toe rest in guides 48 secured to the upper surface of the base member 20. .Between arms 58 secured to opposite sides and extending upwardly from the block 40 is lpivoted at 5| a support 52 fora spindle 54 :arranged to engage the spindle hole in the heel end of thez last.; In order to hold the shoe firmly cn the jack, means are provided for swinging the support 52 for the spindle 54 in a clockwise direction', as viewed in Fig. 2, to causethe toe end of the shoe to be forced firmly against the toe pad 42.u For this purpose a vertically movable rod 56 is threaded into the blo-ck 46 and is arranged to engage the support 52 to the left ofthe pivot A spring 51 seated in a bore in the block engages the underside of the support 52 at the opposite side of the pivot 5| to hold the supporty againstl the rod 56. Splined to the lower end of the rod 56 is a spiral gear 5B which meshes with a spiral gear60 carried by a shaft 62. The outer end of theshaft'82 is provided with a hanvdle 64l by which `theshaft may be turned Iin a direction to rotate the rod 56 and to move it upwardly by reason of its threaded connection with the block 46 thereby causing the shoe to'be held rmly against the toe support.

For moving the heel and toe supports toward and away from each other a screw 68 provided with 'a handle 61 is threaded through the block 46 of they heel support and into the member 24 carrying the toe support, the screw being threaded oppositely at each end so that upon turningit the heel and toe supports are moved in opposite directions so that their relative positions may be adjusted for diierent sizes of shoes. Endwise movement of the screw B6 is prevented by a collar 68 secured to the screw between the heel and toe Asupports and projecting intoa recess (Fig. 2) formed in the base member 20.

In'order to support-theshoe between the heel and toe supports, therebyto prevent distortion of the last by which the shoe is carried with consequent damage to the shoe during the leveling operation, additional Vsupporting members'l2 are provided for kengagement -with opposite sides of the shoe. These supportingmembers. each out with respect comprises a U-shaped plate 14 covered by a piece f of leather or other suitable material 16 of such f the cam surfaces 86 of cam members 38 secured to the top of the base member 20. The arms 84 are formed with laterally extending projections 80 to the outer end portions of which are pivoted spring-retaining members 92 arranged to be engaged by the upper ends of compression springs `94, the lower ends of which seat in recesses formed in the base member 20. The cam surfaces 80 are so shaped as to prevent relative swinging of the arms 84 and 80 about the pivot 18 by the springs 94 when the lower ends of the arms 84 are in engagement with the cam surfaces. Consequently, the springs 84 act to swing the arms 84 and 80 inwardly about the pivots 8| to cause the supporting members 12 to engage the shoe. During this combined swinging movement of the yarms 84 and 80, the arms 84 are swung by the springs 94 relatively tothe arms 80 about the pivots 18 to maintain their lower ends in engagement with the cam surfaces 86 thereby causing the parts 4to be locked by the cams. against outward movement in whatever positions they assume when the supporting mem` bers 'i2 engage the shoe.

When the jacks are in their loading positions, the supports 12 are held apart in inoperative positions so as not to interfere with the proper and rapidv loading of a shoe on thejack. Extending upwardly through the springs 94 and the springretaining members 92 are rods |00 on the upper ends of which collars |02 are held by nuts |04. The lower ends of these rods pass through slots |85 in the base member 28 and through openings in the rearward ends of arms |05 carried by a shaft |08 journaled in brackets H0 depending from the forward portion of the base member 28. The lower ends of the rods 00 are provided with collars I |2 underlying the adjacent ends c-f the arms |06 so that upon downward movement of these arms the rods |00 are caused to move downwardly and exert a downward force upon the lateral extensions of the arms 84 iniopposition to the upward force exerted by the springs 94. Integral with one ofthe arms |06 is a second arm ||4 carrying a cam roll ||6 eneageable with the under surface of an inclined cam plate ||8 secured to the frame of the machine.` This cam plate is inclined upwardly and rearwardly so that the cam roll H6 is caused to move downwardly as the jack moves into loading position. This causes the shaft |08 to turn in such a direction as to move the rearward ends of the arms |06 downwardly to exert a downward pull on the rods |00 thereby moving the lower ends of the arms 84 inwardly and the upper ends of the arms outwardly as permitted by the shape of the cam 86 to carry theV supports 12.out of engagement with the shoe. f

Aftera shoehas been placed onther heel and toe supports. and the heel support hasbeen operated to force the forepart ofthe 'shoe rmly against the toe support, the jackisfeaused to move lfromits vertical positionrearwardlyinto an inclined position to move the shoeinto position to be operated upon by a pressingiform |6,
